The four are charged under a new federal law with selling more than 50 guns in Brooklyn.

A group of gun dealers sold more than 50 firearms to an undercover cop in Brooklyn, federal prosecutors said Wednesday, making sales in a crowded waterfront park and playground.

The dealers brought in most of the weapons from Virginia, and in some cases the weapons they sell have already been used for violence, authorities say — one of them has been linked to half a dozen gang-related shootings, including the 2021 Bedford bloodbath. A Stuyvesant Family Day celebration in which eight people were injured.

U.S. Attorney Breon Peace and the NYPD on Wednesday announced the indictment of the four suspects, calling the case the first public indictment in New York under the bipartisan gun reform bill signed into law by President Biden last June.

The four suspects include Raymond Minaya, 26, and David McCann, 28, from Brooklyn, and Tajhai Jones, 28, and Calvin Tabron, 25, from Virginia.

McCann ran a gang that Peace described as “a network of firearms dealers that endangered our community.”

He introduced the undercover officer to his fellow conspirators, who obtained the weapons from several sources — retailers in Virginia, “ghost weapon” kits, and from criminals who had already used them in Brooklyn, Peace said.

“They thought they were selling these weapons to a drug dealer,” Peace said.

The sales were held in public, many of them taking place in the summer at Canarsie Pier, where children played with their families and kayakers swam.

“Almost all of this happened in the afternoon, in broad daylight, when the merchant would sometimes boldly walk down the street, the public street, carrying bags of dangerous weapons right outside the residential buildings,” Peace said.

Minaya sold one gun that was linked to a series of shootings, including the Aug. 16, 2021 Family Day shooting, sparking a rivalry between East New York and Bedford-Stuyvesant gangs, NYPD Chief of Detectives James said. Essig. .

Another weapon sold by Minaya was used in the December 18, 2021 shooting near the Breukelen homes in Canarsie, which resulted in a man being shot multiple times in the arm, shoulder, neck and base of the skull, prosecutors said.

All of the suspects were charged with conspiracy to traffic in firearms under the new bipartisan Safer Communities Act, which Peace said makes it easier to file federal charges with a stringent 15-year sentence.

The conspirators also sold an undercover cop a pound and a half of fentanyl and another 1.5 kilos of fentanyl-laced crack, authorities said.

Federal prosecutors said Minaya and Jones have extensive violent histories. Minaya was released on parole after being convicted of attempted murder in 2017, and was caught in a shootout at Bay View homes in March, according to a lawsuit.

Meanwhile, Jones was convicted of kidnapping and other crimes in Virginia after a brutal home robbery in 2016.
